' spindles operated positivel by gearing an 'Thesupport for the spindle is then placed arrangement is provided according to the in P n in Whi h it remains in the work- 40 i ti hi h i t i idi a ing position by means of an enlargement or socket which fixes the relative position of r111} of rge iam er as hereinafter dothe spindle in the carrying frame, which scrlbed;

socket is traversed by a tube or sleeve which T upling arrangement carried by the forms part, in the upper part, of the bearl 0f the Spindle is of the kind 45 ing for the journal of the pindle and, at CPlb6d the SIOGClfiCittlOIl Of the co-pendthe lower part, the seating'for the support IIIg'ZIPPhCfltIOIl by h me applicant, to of the same journal of the spindle. This which reference has been made, and, to as- Seat presents a circular opening of a diamsist in the construction in series and the fixeter suificient to permit the introduction of ing in height of the friction discs of the 50 the journal of the spindle with its coupling said coupling arrangement on the journal of the spindle, this fixing is effected by means of a simple key. This result is obtained by forming a mortise upon the spindle and introducing into the same a key having on exterior circular form; and, for avoiding that this part is displaced from its position under the operation of centrifugal force it is retained in a cavity provided in the friction disc, an internal projection bf the said part coinciding with the opening in the key. Thus the friction disc participates in all the movements of the spindle.

The centring of the rings is effected by the suspension of the said rings from a support where by means of a guiding disc provided at its rear or lower part a transverse part slides through a shaft which extends the length of the machine which shaft is divided into sections to facilitate construction) in such manner that the pressure of a single screw fixes the position of the two elements, permitting displacement in two normal directions.

In the arrangement described the centring requires for its equilibrium the suspension of the whole of the rings by means of balancing bars which traverse the spindle carrying frame and are situated in a plane displaced from the rear of the plane of the axes of the spindles at the same time as it permits the passage of the axis of the driving shaft in the example of transmission of movement by means of straight gears.

The accompanying drawings represent a construction according to the present invention.

Figure 1 represents a transverse section taken through the centre of a spindle and the centring supports on the spindle carrying frame showing the common operating shaft.

Figure 2 represents a vertical transverse section of the bearing of the spindle.

Figure 3 is an elevation corresponding to Figure 2.

Figures 4 and 5 show in detail the spindle support respectively in section and in plan.

Figures 6 and 7 show in detail the friction disc disposed normally to the axis of the spindle and respectively in section and in plan.

Figures 8 and 9 show in detail the part which transmits movement from the axis of the spindle to the friction disc, the figures being respectively asection and a plan.

Figure 10 is the general arrangement in front elevation showing the spindles and centring supports and covers of the spindle carrying frame, this view being on a smaller scale than Figure 1.

Figure 11 is a detail view partly in section showing the manner in which movement is imparted to the respective spindles from the common operating shaft.

. In Figure 1 the part 1 represents the up- .per part of, the spindle carrying frame; 2 2' the lower part and the protecting cover respectively for the whole of the mechanism; 3 is the hole in the frame through which is introduced the stationary part or socket l for he spindle which stationary part or socket is of the same diameter as the hole and is securely mounted upon the frame by means of the nut 5. The stationary part or socket 4 carries centrally within it the sleeve 6 and the spindle support 7 which is held in its operative position by the projecting part or rim 8. A. spring 9 applied upon the sleeve 6 within the grooves 10 and 12 permits apart from the automatic centring, to fix the relative position of the stationary part or socket 4 with reference to the sleeve 6, the spring 9 being set within a slot 11 provided on the interior face of the stationary part or socket 4. The sleeve 6 is divided into three sections of different diameter; the first 13 is the sleeve proper, the second 14 of larger diameter permits of the passage of oil which is raised by the spring 21 while the third 15 permits the free rotation of the parts which comprise the coupling described in the specification of the co-nending application referred to.

Upon the spindle 16 is freely mounted the pinion 17 and, to fix the position in height of the same at its lower end, grooves 18 are formed which are parallel and oppositely disposed for the reception of a slotted key 19 of circular form which is maintained in concentric and constant relation with the spindle by the friction disc 20. The upper friction disc 20 is made part with the spring 21 by means of a projecting part at its extremity 22 which engages in a recess provided in the part 20 and in the spindle 16. The orifices 23 permit the 7 outlet of surplus oil for return to supply.

The part 24 fixed upon the spindle 16 by pressure applied to its cone of contact comprises three surfaces, the first is conical for the centring of the tubes upon which the thread is to be wound, the second. surface 25 is cylindrical and serves to fix the position of the cover 28, and the third surface 26 is a protruding circular rim which serves to limit by contact with the inwardly protruding end of the part 27 screwed upon the socket L, the

upward movement of the spindle 16 caused by the operative when he withdraws a bobbin either because the bobbin is spent or in order to join a broken thread, and thus to avoid the excessive displacement of the spindle 16 which would cause the fracture of the pinion 17 and of the wheel 43.

The ring 29 is fixed by pressure in the part 30, which is provided with an orifice 31 in which freely passes the screw 37, and con prises at its lower part a guide plate 32 normal to the shaft 3 1 upon which is adjusted and slides a part 33. The part 33 is slotted at 35 so that thus the screw-threaded pin 37 which is screw-threaded within the part 33 the ring 29. The whole of the assembly of rings and supports rest upon'the part 38 which is screw-threaded at 39 so as to be capable of receiving anupward or downward movement upon rods 40 passing through uides 41 exactl in the same wa as in known a 7 V spinning and twisting machines.

The characteristic of this system of rings is that the alignment of the bars and guides 40, 41 is in a plane displaced to the rear of the plane formed by the alignment of the spindles 16.

The part 42 represents the common driving spindle upon which is mounted the respective driving wheels 43 which transmit rotary movement from the shaft to the spindles. The pinion 1'? causes the rotation of the spindle 16 by reason of pressure of the rings 20 against the ends of the pinion, produced by the spring 21 in a maner similar to that described in the specification of the copending application No. 261,951 dated 15th March 1928.

The cover 2 is fixed in its position and its lower edge is held within a groove 44, while at the upper part it is held in position upon the spindle carrying frame by means of screws 45. The cover is provided as a plate 46 of uniform thickness having at each side two parallel transversely disposed parts 47.

The type of construction described having cover plates of short length permits of the withdrawal of a single cover plate (which protects a number of spindles) without the necessity of uncovering the neighbouring spindles.

In Figure 2 the numbers 6, 7 8, 10, 12, 13, 14, 15 and 23 are applied to the same parts as in Figure 1. The sleeve 6, as represented in detail, is provided with a groove 12 in which the spring 9 (Fi ure 1) may lie. Furthermore a groove 48 permits the return of oil in excess which passes through the orifices 23. 23 to the supply. An opening 49 provided in its lower part permits the driving wheel 43 to effect its engagement with the wheel 17 (Figure 1). The width of the said opening permits the introduction of the support represented in Figures 4 and 5 when this is presented with the parallel faces 50, 50 adjacent the sides of the opening and the parts 7 and 8 (Figure 4) are caused to coincide with those also lettered 7 and 8 (Figure 2) whereby the support may be thus set in working position.

Figures 6 and 7 represent the friction disc which is disposed normal to the axis of the spindle and is provided with a projecting part 51 to effect the transmission of movement to the spindle by means of the key 19 represented in Figures 8 and 9 in the opening 52 of which is engaged the projecting part 51 (Figures 6 and 7).

Figure 10'represents an external view of the whole of the mechanism described, the same figures indicating the parts detailed in the preceding figures. v
